Research summary

Graphene-based materials and porous carbons for energy storage and sensing form the central thread. A one-step fabrication produced macroscopic graphene hydrogels by ferrous-ion-induced reduction of graphene-oxide sheets with in situ deposition of α-FeOOH or Fe3O4 nanoparticles, yielding pH-controllable multifunctional graphene monoliths suitable as adsorbents for water purification [8]. Free-standing graphene paper (0.2 g/cm^3, 15 Ω/sq) was prepared in a single step by simultaneous assembly and chemical reduction of graphene oxide on a Teflon substrate, and the resulting graphene-PANI composite paper served as a supercapacitor electrode with 763 F/g specific capacitance and good cycling [9]. A piezoresistive sensor with ultra-high pressure sensitivity (0.26 kPa^-1 below 2 kPa, 9 Pa minimum detectable) was built from a graphene-wrapped polyurethane sponge with a fractured-microstructure design suitable for artificial skin [7]. Nitrogen-doped porous carbon nanofibers made by carbonizing polypyrrole-coated CNFs gave a reversible 202 F/g supercapacitor specific capacitance at 1 A/g in 6 M KOH [3]. Bimetallic-MOF-templated porous carbon with CoNx moieties and N/Co/P dopants outperformed Pt/C as an ORR electrocatalyst in alkaline media [5]. Hydrothermal carbonization (HTC) of biomass was reviewed as a low-cost route to functional carbon materials [2]. Electro- and photocatalysis cover several reactions. An alkaline-water-splitting review traced 100+ years of mature electrolyzer technology and recent electrochemical advances toward zero-carbon H2 [1]. The MoS2/CoSe2 hybrid catalyst grown in situ exhibited HER onset at -11 mV with low Tafel slope and high turnover in acidic media as an earth-abundant alternative to Pt [10]. Porphyrin-MOF PCN-222 selectively captured and visible-light-photoreduced CO2, with ultrafast transient-absorption and time-resolved photoluminescence spectroscopy showing that a deep electron-trap state in PCN-222 inhibits electron-hole recombination [6]. Nanostructured metal chalcogenides were reviewed across synthesis, modification, and applications in fuel cells, photoelectrochemical water splitting, solar cells, Li-ion batteries, and supercapacitors [4].
